Abstract: An Integrated Dewar Detector Assembly (IDDA) is presented. The IDDA comprises: a cold finger base; an elongated Dewar envelope having a proximal end associated with the cold finger base and a distal end comprising an optical window; an elongated tubular cold finger located inside said elongated Dewar envelope and having a proximal end at the cold finger base and a distal end for carrying a detector so as to expose the detector to incoming radiation through said optical window; an internal front support member extending from an inner surface of the Dewar envelope at its distal end to the distal end of the cold finger; and at least one wideband dynamic vibration absorber assembly located outside the Dewar envelope and attached to at least one location on an exterior surface of the Dewar envelope, said dynamic vibration absorber thereby attenuating vibration of the cold finger and the detector.
